The gap between the two front wheels and the wheel eyebrows is different. The left wheel is 4 fingers wide and the right wheel is 2 fingers wide. The mechanic said the suspension should be changed. Is it necessary? Tire position judgment: 1, left wheel position judgment: I need to know whether the left wheel pressure is used to avoid tire compaction line or potholes and stones. My line of sight passes through the left wiper projection node surface object, and my left wheel moves. The pressure ratio diagram of this object is that the wiper node surface line coincides with the tire line pressure. 2. Driving 60 km offline: It is safer for me to drive 60 km offline. The intersection line of A-pillar of cotton-passing board coincides with the off-line 60 km. 3. Judge the position of the right wheel: I can see it through the target intersection tire of the right wiper. 4. Drive 60 kilometers on the right side of the road. The target overlap of the sprinkler on the right side of the road is 60 cm away from the road. 5. Stop to the right. The cursor nodes on the right overlap slightly to the left. 10 cm pull over. How to judge the distance between the front end of the car and the front car: Judging the front end of the car: The car example assumes that the front height is about 1.7 ~ 1.8m, the foot height is about 10 cm, the knee height is about 45 cm, and the hip height is about 70 cm. The distance between the car front end and the car body is 3m 2 when the car front end moves and stays from the foot surface or heel facing the car body, 1m 3 when the car front end is raised, and the distance between the car front end and the car body is 0.3m. The distance between the front end of the car and the car body is judged as 1, and the edge of the front bumper of the car is about m along the windshield. 2. The windshield is about two meters along the edge (knee) of the front bumper; 3. The windshield is about three meters along the front tire (or surface); 4. The left mirror is along the horizontal line of the photo plane viewed from the position of the car. The right mirror judges the car distance: 1, and the car shadow accounts for about 3 meters of the total car distance of the mirror; 2. The distance between the car shadow and the mirror is about 5 meters; 3. The distance between the car shadow and the mirror is about 9 meters; 4. The distance between the car shadow and the mirror is about12m; 5. The left rearview mirror looks at the position behind the wheel housing (reflected by the door handle, the horizontal line of the car body or the bottom line of the rearview mirror). 6. The windshield of the endoscopic fluoroscopy window is open. Judging the distance between cars: if you look at the edge of the lights, the trunk is about three and a half meters away from the car; If you look at the joint between the hood and the front windshield, the trunk is meters away from the car; If you look at the height of the front windshield, you can basically judge the position of the vehicle (wheel position and front position): 1, and judge the position of the roadside windshield (the left column of the left wheel windshield is right10-15cm; 5-10cm to the left of the right wheel windshield line); Distance from the roadside to the mirror 2. Determine the position of the right wheel (car part or right wiper): three positions on the right side of the hood.
